HYDROGEN-SULFID GENERATOR.

y scription of the invention, such as will enable others skilled in the art to whichit appertains to make and use lthe same.

`The present invention relates to improvements in gas generators, and it has for its ,principal objectthe production of an exceedingly simple, inexpensive Vand efficient device, designed primarily for use in the generation of hydrogen sulfid gas.

V4The invention more especially resides in the particular construction of both the basket or holder for the ferrous sulfid, and the support upon which the holder and bell-jar nremounted, and it further residesin the provision of devices for holding the bell-jar against upward movement, and in the partic'ular form of such devices.

The preferred embodiment of the invention isillustrated in the accompanying drawings in which corresponding parts are designated by the l same reference characters throughout the several views.

Of the said drawings, Figure 1 is a vertical sectional view of the complete apparatus. Fig. 2 is a plan view of the generator. Fig. 3 is a perspective View of the support. Fig. 4 is a plan view of the storage tank.

Referring more particularly to the drawings A designates generally the generator section of the apparatus, and B the storage and cooling tank.

' The generator, as shown in Fig. 1, comprises a cylindrical receptacle 1 formed of glass or porcelain or other suitable material, and a bell-jar 2 disposed therewithin. The bell-jar is supported by a spider 3 which rests upon the bottom of the receptacle 1, the dimensions of the spider being slightly less than the diameter of said receptacle. Each arm of the spider has formed therein a seat 4 located intermediate the upper and lower faces thereof, said seats resulting from the cutting away of a portion of the outer ends of the arms of the spider. The bottom walls of these seats are arranged to receive the lower edge of the bell-jar which rests thereupon. The upper face of the spider is adapted to support a holderV or basket 5 in Specification of Letters Patent.

which the ferrous sulfid is placed, said basket being likewise constructed of any suitable vitreous material. The side wall of the basket is perforated adjacentits lower edge, and the bottom thereof is likewise formed with a series of perforations.

Owing to the formation of the seats 4 above referred to, it will be apparent that the lower .edge of the bell-jar extends below the bottom of the basket.

At its top the bell-j ar is provided with an axial opening in which a rubber cork 6 is fitted, and with a series of exteriorly located shoulders 7 each of which has its upper face notched, as indicated by the numeral S.

`'llhesenotches are arranged to receive tiewires 9 whose opposite ends are fastened to the side wall of the receptacle 1, as is shown in Fig. 1, the provision of said wires tending to hold the bell-j ar in place upon the spider,

`and to prevent its upward movement. The

receptacle 1 is in turn provided adjacent its lowerV edge with an opening in which is fitted a'rubber cork 10, the corks 6 and 10 being fitted in their respective openings from the inside, z'. e., small end outward. The last-mentioned cork is formed with an axial opening through which extends a short valved drain pipe 11 whose inner end extends into the interior of the receptacle 1, while the cork 6 is provided with a similar opening in which is fitted the bent upper end of a glass tube 12 whose lower end communicates with a similar tube 13 which extends into the interior of the storage tank.

The storage tank, as shown in Fig. 1 comprises a vitreous jar 14 having opened upper ends and an aluminum bell 15 fitting loosely within said jar or shell and capable of a vertical movement under the pressure of the gas introduced thereinto. The pipe 13 above referred to is L-shaped as shown, its horizontal arm extending through an opening formed in the side wall of the shell 14 while its vertical arm terminates at a point slightly above the plane of the upper edge of the shell. This pipe therefore serves as an inlet pipe. The outlet pipe 16 is similar in appearance to the inlet pipe, and its vertical arm is disposed adjacent that of the inlet pipe, while its lower arm likewise extends through an opening similar to that through which the horizontal arm of said inlet pipe extends, leakage at such points being prevented by means of rubber corks 17 tted from the inside in said openings,

Aof the shell 14 and are fastened thereto.

said corks being provided with axial openings through which the pipe arms above referred to extend. The outer end of the horizontal arm of the outlet pipe is provided with a cut-ofi1 valve of any preferred type.

The top of the bell 15 has rigidly secured thereto an exteriorly located cup V18 arranged exactly centrally thereof. The bottom of this cup has secured thereto in turn the lower end of a vertical metal wire 19 whose upper end projects loosely through an eye formed in the outer end of a horizontal rod 20 carried by a second vertical rod 21, the last-mentioned rod being rigidly connected atits lower end to a metal band or bands which embrace the upper portion The cup 1S is designed to be weighted in any manner, preferably by the introduction of shot thereinto.

The operation of the apparatus as a whole may be described as follows. The basket 5 is filled with ferrous suld in lumps, after which it is placed upon the upper face of the spider and inclosed by the bell-jar 2 whose lower edge or mouth rests upon the bottom wall of the seats 4. Hydrochloric acid is then poured between the bell-j ar and` the receptacle, after said bell-jar has been fastened in place by the tie-Wires 9. Pressure within the bell-jar is then relieved, allowing the acid to rise in the bell-jar into Contact with the ferrous sulfid, whereupon the generation of the hydrogen sulfid gas will commence, the acid iiowingv through the perforations in the basket, as will be apparent. The gas generated will flow through the tube 12 and the inlet tube 13 into the interior of the bell 15, which latter is partially filled by the water previously poured into the shell 14. hen the pressure of the gas in the upper portion of the bell 15 is suliiciently great to overcome the pressure of the weights within the cup 18, said bell will rlse,

.being guided in its movements by the pasp the bell through the outlet pipe 16, it being apparent that its pressure will be maintained approximately constant owing to the provision of the weighted cup, such pressure being determined by the weights disposed therewithin.

Evaporation of the gas from the water is prevented by a liquid seal 24 formed by pouring a layer of mediumly heavy oil upon the water between the walls of the shell and bell.

That is claimed is:

A gas generator, comprising in combination, a liquid receptacle having an open top; a spider disposed within the receptacle and arranged to rest upon the bottom thereof; a bell-jar disposed within said receptacle and supported solely by the arms of the spider, said bell-j ar being provided at its upper end with exteriorly-located shoulders; tie wires extending across the open top of the receptacle and having their ends fastened to the wall thereof, said wires being engaged with the shoulders on the bell-jar, to hold the latter against upward movement; and a perforated basket disposed within the bell-j ar and supported solely upon the upper face of the spider, said basket having its bottom disposed above the lower edge of the bell-j ar.

In testimony whereof, I affix my signature, in presence of two witnesses.
